TRANSFER GEARBOX WITH INTERAXLE DIFFERENTIAL OF SNOW AND SWAMP VEHICLE Russian patent published in 2025 - IPC B60K17/346 F16H3/44 F16H37/08 F16H57/31 

FIELD: vehicles.

SUBSTANCE: invention relates to transmission of multipurpose snow and swamp vehicles. Transfer box with interaxle differential comprises housing made in the form of U-shaped figure from aluminium. Housing is connected to the cup-shaped cover through the plate. On the input shaft there is a hub on which a gear wheel and a coupling are fixed. Input shaft outer surface is stepped. On its one end there is a through hole and a blind longitudinal hole perpendicular to its longitudinal axis. Output shaft is fitted on rear axle aligned with input shaft. In the housing there is an output shaft on the middle axle, on which a flange is installed. Sun gear is placed in the carrier; at that, a movable coupling is installed on one of the stages of the carrier along the outer surface. Carrier is fixed on the shaft sleeve. Gear is installed between movable coupling and carrier with possibility of engagement with gear. Gear wheel is installed on the shaft by means of a bushing, having the possibility of engagement with a gear installed on the input shaft. On the shaft of the sun gear there is a toothed bushing. Both ends of the sun gear shaft are provided with splines. Movable toothed coupling is installed on the front axle shaft. Satellites are able to transmit rotation to the epicyclic gear made integral with the external toothed rim and to the sun gear. Gear wheel has possibility of engagement with epicyclic gear.

EFFECT: longer life of transmission.
